Description
CropRx is a hybrid crop diagnostic service combining instant AI analysis with human Plant Doctor validation. Farmers send a crop photo via WhatsApp and receive a prescription-style PDF covering disease identification, treatment, dosage, and prevention — in their local language — within minutes to 24 hours. No app download required.
The Problem We Solve
- Farmers rely on pesticide sellers who push products for profit, not solutions.
- Existing AI apps (Plantix, PlantNet) give generic diagnoses with no local context or language support.
- No accountability exists when wrong advice causes crop loss.
- Result: wrong treatment, chemical overuse, yield loss, food insecurity.
Real example: A rice farmer in Bogura, Bangladesh applied fungicide for 3 weeks with zero improvement. Root cause: the pesticide seller gave him the wrong product class entirely. CropRx would have caught this in minutes.
How It Works
- Farmer sends crop photo + details via WhatsApp.
- AI vision API performs instant first-pass diagnosis.
- High confidence → prescription auto-delivered in local language within minutes.
- Low confidence → case escalated to Plant Doctor (Fahim) for human review.
- Full prescription PDF delivered within 24 hours.
- Day-7 follow-up check-in on treatment outcome.
